Our wedding will be in Bellagio, Lake Como, Italy. The fastest/easiest option is to fly into Milan (MXP). You can rent a car from the airport however a car is not necessary once you're in Lake Como (see below for more info). The other option is to take the train/ferry. The train takes ~ 1.5 hours and there is one transfer mid-journey. From there you will take a beautiful ferry ride from Como to Bellagio. We have done this multiple times and it's quite feasible to navigate! The hardest part is managing your luggage so keep that in mind. We can provide exact instructions with every step along the way for you once you have your flight arrival time in Milan. If you are spending time in Milan before coming to Lake Como there is a direct train from Milan Central.
You can also fly into Zurich (ZRH) if you would like to enjoy some of the Swiss Alps along your way! You would rent a car there and drive south ~3.5 hours to Lake Como.
We have also done this route once and it too is very manageable.
